HART, OF NEW BRITAIN, CONNECTICUT, ASSIGNOR 'IO REMINGTON TYPEWRITER COMPANY, OF ILION, NEW YORK, A CQRPOBATION OF NEW YORK TYPEWRITING MACHINE Application filed March 1,

My invention relates [to typewriting ma chines, and more particularly to work sheet controlling and gaging means by which work sheets may be quickly, and successively, introduced and accurately positioned in the" machine.

More specifically considered, my invention relates to paper guiding, and end-stop devices by which work sheets successively introduced rearwardly from the front of and beneath the platen may be quickly and accurately positioned.

he main objects of the invention, generally stated, are to provide improved and comparatively simple devices of the character specified, which are in the nature of attachments that may be readily incorporated in existing machines without modifying, or ma-' terially modifying, the existing structural features thereof, and which when desired may be readily attached to or detached from the machine as a single unit. A further object of my invention is to provide comparatively simple and compact devices of the character specified which are highly efl'icient in use and with the aid of whichwork sheets may be positioned under varymg conditions of use.

To the above andother ends which will hereinafter appear, my invention consists in the features of construction, arrangements of parts and combinations of devices to be set forth in thefollowing description and particularly pointed claims.

hepresent invention has some of the same general objects in view as the construction disclosed in the'a'pplication of Cloyd E. Burns filed July 13, 1926, Sr. the nature of improvements on the construction disclosed in said application.

The devices of the present invention were devised more especially for use in the Rem- '15 N 0. 122,239 and is in Y ington front feed billing machines, certain features of which are disclosed in my application Sr. No. 120,403 filed July 3, 1926. While the devices of the present invention are particularly useful in the machine referred to, it should be understood that their use is not restricted to such machine, but that theymay be employed in various forms of typemachines wherever found kinds of billing operations, where two or more work sheets are to be correlated in-themachine and printed at a single operation.

' through However, 'I do not deem it necessary to describe specifically the many different forms of billing operations in which the said Ina-- chines may be used. It is sufficient for an understanding of the present invention to describe in general terms one mode of billing that may be successfully carried out with the aid of said machines and perhaps briefly refer to some of the various other methods in connection with which the machines-maybe employed together with the paper end-stop and other devices of my invention.-

One method of using the said machine which will be specifically referred to, is its employment, for example, for simultaneously, or at one writing, making out a bill or invoice and making corresponding entries on a record or register sheet which receives the entries written on all of the individual bill or invoice sheets. In the example referred to the register sheet and its accompanying carbon sheet remain in the machine. Means are provided for quickly entering a bill or invoice sheet and accompanying carbon sheet rearwardly into the machine from in front of the platen, and accurately positioning them in proper correlation with the previously introduced register sheet and the printing line. The entries may then be made on a bill sheet andthese will be transferred the interposed carbon sheet to the register sheet. The bill sheet and accompanyin carbon sheet are then rapidly withrawn rom the machine without disturbing the register sheet, and another bill sheet with accompanying carbon sheet may' then be quickly introduced and positioned as before,

and so on.

In the example of the billing operations explained above the end stops and guides of m present invention are intended to coact wit the bill or invoice sheet, to quickly and accurately effect a positioning thereof under varying conditions. It should be understood, however, that in other uses of the machine, the said stop devices of my invention will coact with other sheets in a variety of ways, some of which will be hereinafter explained.

With the foregoing general explanation, I will now proceed to briefly describe so much of the said machine as is necessary to arrive at an understanding of embodiment therein. The frame of the machine is of the usual construction and includes a top plate 1 carrying fixed guide rails 2 (only one of which is shown), oppositely groove to receive cross anti-friction bearing rollers 3. These rollers are'also received in oppositely grooved carriage rails 4 at the front and rear of. the carriage (the rear carriage rail only being shown said carriage rails being connected with t e end bars 5 of the carriage.

The carriage, which is I stantially to my invention in its power driven in the usual manner, is thus supported and mounted to travel from side to side of the machine over the top plate under control of the usual escapement mechanism (not shown), and in some instancesunder control of the usual tabulator mechanism.

The platen 7 is carried by the platen frame in the usual manner, said platen frame comprising end plates 8 united by suitable cross bars. The platen frame is connected to the carriage or truck by links 10 in the usual manner, which links ordinarily guide the platenframe in its case shifting movements. The present machine. however, is intended to write only with capital letters or upper case characters and there is, shifting movements of the platen and frame; the platen frame being firmly held in its upper case position on the carriage, where it will coact with the outermost types 11on the type bars 12. These type bars are mounted in a type bar segment in the usual manner to swing upwardly and rearwardly to printing position where they strike against the front face of the platen.

The usual ribbon vibratpr mechanism is employed so as to interpose the ribbon in the path of the types 11 at each actuation of a type bar. Only the upper end portion-of the ribbon vibrator 13 is shown, it being understood, however, that the vibrator is guided for up and down movement on the type guide 14 in the usual manner.

As in the constructi n disclosed in my said prior a plication, the e are two curved par de ectors 15 and 16 employed beneath the platen, one arranged above the other and maintained spaced apart by intermediate spacin members or blocks 17 located near the en s thereof. Generally speaking, these deflectors beneath the platen conform subthe curvature of the latter, or are substantially concentric therewith, and extend substantially throughout thelength of the platen. As thus constructed there are two separate channels provided, one of which is the open channel 19 between the two deflectors, and which is bounded at its ends by the spacing members 17, either or both of which may constitute side edge guides or gages for cooperation with one or both side edges of the channel 19. The other separated channel 20 is provided between the under surface of the'platen and the u per deflector 15. It will be seen that the orward edge of the deflector 16 terminates in advance of the forward edge of the deflector 15. The deflector 16 is continued up at the rear to provide a paper table a, bent rearward at its upper edge portion, as at b, and terminating in an therefore, no case platen a sheet or sheets introduced into nected at its ends united deflectors and 16,

platen frame. In

dare prevented from entering the channel 20.

In order to facilitate duction of sheets into the channel 152 from in front of the platen there is provided in accordance with the invention disclosed in my prior application, a guide, shield, or paper deflector 24 that is movable on the carriage from a substantially horizontally disposed inefl'ective position, shown in dotted lines in Fig. 7, to a downwardy and rearwardly inclined effective position, shown in full lines in said figure, and vice versa.

The deflector 24 has at the ends thereof, each of said arms being pivoted at 26 on an end plate 8 of the platen frame. In this manner the deflector 24 is mounted for pivotal movement .from'the ineffective dotted line position, shown in Fig. 7, where it is out of the paths of the types, to the full line osition where it crosses the printing line and extends in the paths of the types. In this last mentioned position the deflector overlaps the forward 16 and forms virtually a" edge of the deflector continuation of the channel 19 to aid in quick ly and effectively introducing work sheets backwardly beneath the platen into the channel19.

It is unnecessary, present invention, to

disclose the means by which this deflector 24 is actuated and by which the fine wire line indicator 27 is auto-' matically shifted 'fromthe effective, to the ineffective position in Fig. 7, when the deflector 24 is shifted from the dotted to the It also is unnecessary to disclose herein the means by which these devices are automatically controlle by a shifting of the feed rollers 28 v (diag mmat'ically shown) from the ineffective position shown in Fig. 7 into contact with the platen or a work sheet thereon. Nor 1s it necessary to dlsclose the means for"automatically lowering the ribbon vibrator from the full to the dotted line posit n in Fig. 7 when the deflector 24 is moved from inefi'eetive to effective position, thus giving ample clearance between said deflector and vibrator. All of such means are embodied in said here ihdefore mentioned Remington machines.

It will suflice for the purpose of arriving at a better understanding of this invention, in

the backward intro-' depending arms 25 for the purpose of the its present embodiment, to bear in mind that the parts referred to operate in the general manner indicated above.

As disclosed in said plications a set of feed rollers 30 coact only with the worksheet Rand its carbon. sheet previously filed apshifting movement into and out of cooperation with the work sheets with" which they coact is disclosed in the'hereinbefore referred to Remington machine and need not be specifically described herein. In accordance with the present invention certain work sheet gaging means, or paper end-stops, coact with the bottom edge of a bill. or invoice sheet B introduced through the channel 19, and these stops as well as certain paper guiding devices, are adjustable supported and detach ably mounted on the paper table a and may be readily applied or detached as a single unit. These devices of the present invention, and the manner ofmounting and ads justing them, will now be described.

A casting, designated as a whole by the reference numeral 31, constitutes a support for a set of devices of my present invention,

which devices are adjustable on said support,

and the support itself is be readily applied to and detached from t e carriage with said devices and also may be adjusted to difierent'positions with said devices longitudinally of the platen. I preferably make this support of aluminum and in practice prefer to employ two of such supports, each equipped with said devices in alike manner and I locate the sup orts at different positions longitudinally of t is platen, to detachably and adj ustably secure each support to the upper edge portion 6 of the paper table a and to this end I construct the sup. ports 31 as follows:

Inasmuch as each support 31 and the parts carried thereby are alike, it will suffice to describe one. of these stood that such description will a ply to each of them. The support3l is sl dtted at 32 throughout its length to provide a bearing slot closed at its rear side and of a width corresponding substantially to the thickness of the upper edge portion 6 of the paper table which is received therein and constitutes a support for the members 31 and the parts carried thereby. In order-to hold or clamp each support 31 in theposition to which it may be adjusted along the paper table, and enable it to be removed when desired I proas indicated in Fig. 1. I prefer units, it being undervide a suitable clamping or clutching means that may be readily released. In the present instance such means are in the nature of'a 'head 37 and an outer integral cylindrical finger piece or head 38 both of which fit loosely in the bore 35. A coiled expansion spring 39 bears at its opposite ends against the heads 37 and tends to move the wedges outward away from each other. This results in each wedge acting on its associate ball 33, tending to force it into clutching engagement with the part b of the paper table, when said part is contained in the slot 32, and firmly hold the supporton the paper table.

- In order to release the clutch it is merely necessary to press the associated finger pieces 38 towards each other, thus releasing the pressure of the wedges on the balls and freeing the clutch. It will be understood that each ball 33 is received between the two companion heads 37 and 38 and that therefore the wedges cannot be displaced from their bore as long as the balls remain in their pockets 34. In order to readily assemble the clutch members, and enable them to be taken apart when desired, I provide a tapped opening in register with each pocket 34 and provide a filling screw which is received in and normally closes its opening, the inner end of each screw being substantially flush with the lower wall of the slot 32. When is ready for use. a The support assembling the clutch members the screws 40 are removed and the balls 33 are introduced through the tapped openings into the pockets 34 while the wedges are held against the pressure of their spring 39. The screws 40 are then threaded into place and the clutch 31 is provided with an inclined supporting face .41 (see Fig. 7 bordered on each side with an upstanding flange 42. This supporting face and side flanges act as a support and guide for an auxiliary supporting member, designated as a whole bythe reference numeral 44, and which is shown detached in Fig. 4. This member has parallel side flanges that terminate at their lower ends in upstanding cars 46 having registering openings 47 therein. A spindle 48 (see Fig. 6) receives a bearing in said openings and is provided at one end with a laterally bent arm 49 that constitutes a finger piece by which the spindle may be turned in its bearings. Fixed on said spindle by a pin 50, or otherwise, is an eccentric 51-that constitutes a clamping member, as will presently appear. This eccentric extends between the as at 52, and

- paper table a,

ears 46 and the high portion of the eccentric moves towards and away from the outer face of the auxiliary support, depending on the direction in which the finger piece 49 is turned. The bottom wall of the auxilia support 44 is slotted longn'tudinally thereo each side wall of the slot is cut away to provide a web 53, as shown in Figs. 5 and 10. The stem of a screw 54 passes through a circular opening in the sup I ort 31 and through the slot 52 in the mem er 44. This screw is provided at its forward end with a head 55. flattened at its sides, as indicated at 56 in Fig. 5, to engage opposite parallel side walls 57 of the cut-out in the face of the member 44 and adapted also to bear down on theweb 53 thereof. This prevents the screw 54 from turning while a thumb nut 58 on therear threaded end thereof is turned. An extension or hub 59 on the thumb nut bears at its forward end against the rear side of the support 31 and when the nut is tightened the head of the screw will firmly clamp the auxiliary support 44 in its adjusted position on the support 31. When said screw is loosened the auxiliary support 44 may receive a sliding adjustment in an inclined plane towards and from the platen, from, for example, the position shown in Fig. 7, to that indicated in Fig. 9, or vice versa, or to any intermediate point. 'This adjustment of the member 44 is parallel with the face of the the member being supported and guided by the face 41 and the side flanges 42 of the support 31. When thedesired point of adjustment is obtained, the thumb-nut 58 is tightened, firmly clamping the member 44 longitudinally extending groove or cut-out in j the face of the auxiliary support 44, with the fiat sides of said head engaging the walls 57 as described, even though the thumb nut be loosened to the limit of its movement on the screw. In order to limit the releasing movement of the thumb nut I prefer to provide a slight head or burr 61 on the rear end of the screw 54.

Supported on the forward face of the auxiliary supporting member 44 is a thin flexible metal arm 62-which is-shown detached in Fig. 3. The width of'this arm is such that it may be received between and guided by the side flanges 45 of the auxiliary support 44. This arm constitutes a carrier for a paper end-stop 63 formed by an enlargement on the lower end of the arm and against which the bottom edge of a work sheet may be arrested,

as will hereinafter appear. The arm 62 may the position represented in the understood from v thus be adjusted towards and from the laten on exibilit tion around the platen when the arm is adj usted to a lower position, as indicated, for example, in Fig. 9. The arm 62 preferabl has fixed thereto a forwardly pro ecting pm 64 which maybe riveted to the arm, as indicated at 65 in Fig. 11, and firmly held thereto by a reinforcing washer 66. This pin provides means that facilitate an adjustment of the arm on its support towards and from the platen, and at times acts'as a stop to limit the range of such adjustment and to prevent the arm from being accidentally detached from its supporting means.

Arranged. above the flexible arm and loosely fitting between the side flanges 45 of the auxiliary support is a stiff sheet metal paper guide 67 shown detached in Fig. 2. This guide has forwardly bent ends 68 and 68 between which is located a centrally disposed longitudinally extending slot 69 in which may be received, at times the pin 64 on the flexible arm, as for example, when the parts assume some such adjusted relation as that indicated in Fig. 9.

It will be understood that the paper uide 67 is at all times located directly bene'at the eccentric 51 so that when the latter is turned to clamping position it will bear down against the paper guide. The latter will in turn bear down against the underlying flexible arm 62 pressing it against the forward face of the auxiliary support 44. Means are thus provided for firmly clamping and holding the paper guide and end-stop carrying-arm in the positions to which they may be relatively adjusted on the auxiliary support, which in itself is adjustable on the support 31, as hereinbefore pointed out.

In thus supporting the paper guide 67 on the support 31, it will beseen that said uide is arranged parallel with the paper ta le (1 providing an intervening space 70 between the under side of said guide and the front face of the paper table a. It will be seen moreover that such space '70 forms in eflect a continuation of the passage or channel 19 between thecurved deflectors 15 and 16 and receives and guides sheets passing therefrom.

en in condition; for use the paper guide 67 will be adjusted on its sup ortdown to d iawings with thereof resting on top 22 of the deflector 15, formlng a continuation of the channel 19, as hereinbefore indicated. This position of the guide 67 is maintained irrespective of the position to which the companion end-stop 63 and its arm 62 maybe adjusted, as will be the lower bent end 68 of the looped portion 8 and 9. Fig. 7 represents the highest point of adjustment of the stop 63, Fig. 9, one of thelower points of adjustment thereof, and

, eccentric 51.

a consideration of Figs. 7

Fig. 8 an intermediate point'of adjustment of said stop. It will be seen that at times the i stop 63 1s located in the space 7 0 between the paper guide 67 and the paper table (1, whereas at other times it is located in the channel 19 between the two paper deflectors 15 and 16.

When it is necessary to effect a relative adjustment between the members 62 and 67 which will bring the pin 64 outside of the slot 69, and beyond the upper end 68 of the guide 67, as shown in Figs. 7 and 8, such adjustment may be effected as follows:

The eccentric 51 is released and the guide 67 is adjusted up on the support 44 until the lower end 68 of the guide is adjacent the At this time the upper end of the guide may be tilted forward around the eccentric to free the slotted portion of the guide from the pin 64. The flexible arm 62 may then be adjusted up with the aid of its pin until the latter is beyond the upper end 68 of the guide. The guide 67 is then turned back against the flexible arm and adjusted to effective position and the flexible arm may then be adjusted towards or away from the platen, or around the same to properly locate the end-stop 63. The eccentric is then turned to clamping position and the guide and flexible arm will be firmly of relative adjustme t.

It will be understood that the pin 64 coacts held in their positions with the eccentric 51 to limit the downward adjustment of the arm 62. Therefore, it is necessary in order to afford an adjustment of the arm 62 to its lower positions (one of which is indicated in Fig. 9) to carry the eccentric 51 down from a position where it obstructs the requisite downward adjustment of the pin 64 and the arm to which it is connected. This resultis attained by adjusting the auxiliary support 44 down on the support 31, as indicated for example in Fig. 9, which affords an adjustment of the end-stop 63 to its furthest advanced position.

While I have referred specificallyto one end-stop 63, guide 67 and associated parts, as hereinbefore indicated, I prefer to employ two sets of such devices as shown in Fig. 1, the devices of each set being adjustable together as a single unit with their support 31 longitudinally of the platen to accord with bill sheets, etc., of difi'erent'widths; each sup port 31 also being readily attachable to and detachable from the paper table with the aid of the ball clutch.

After the re ister sheet R and its carbon sheet R have een positioned as described, a bill or invoice sheet B is introduced rearwardly into the channel 19 and positioned with the aid of the line indicator 27 for thepaper end-stops 63 are then adjusted down to contact with the bottom edges of the bill sheet thus introduced and are secured in their adjusted positions. The writing may then proceed and each subsequently entered bill sheet may be quickly entered and positioned with the aid of the end-stops 63 to begin the first written line thereon, while the register sheet and its carbon remain in the machine the register sheet taking an accumulation o the written bills.

It will be understood that the part 31 may be regarded as a support adjustable longitudinally of the platen and the devices 44 and 62 as a two-part stop-carrying member mounted on said support, the two parts (44 and 62) of said member being mounted for. relative bodily adjustment one on the other in a line feed direction, one of said parts (62) 2e3ing flexible and carrying a paper end-stop I have hereinbefore indicated that the present machine is capable of a very wide range of use, and may be employed with or wlthout slight change in almost any character of billing or like work wherein two or more sheets are employed, and where one or more work sheets are introduced into and removed from the machine, while another or other sheets are retained in the machine and a certain correlation is required between the sheet or sheets retained in the machine and those introducedtherein from time to time. Therefore, the end stops may be employed in a variety of ways.

For example, let it be supposed that (the machineis to be used as a check writing machine, in which a copy is to be made of all checks as they are written. In this event the checks only would be rearwardly introduced into the channel 19, the end-stops 63 being advanced to some such position as j that indicated in Fig. 9 and permitted to remain in such position indefinitely. The record of the checks written would be manifolded through the carbon sheet R to the record sheet R, both of which latter sheets are fed through the se arate channel 20. In this event the sheet would constitute a vpay-roll or register sheet, the use of the stops 63in check-writing providing for the adjustment of such stops to accord with checks of different depths.

Generally speaking, the sheet R, if used when copying bills or invoices, may constitute a sales sheet or a distributing sheet. If used in check-writing it may-constitute a pay-roll or register sheet. In each event, however, the sheets R and R remain in the machine while the bill sheet and accompanying carbon or the check, as the case may be, are removed after each writing, and new sheets entered in place thereof with the aid of the end-stops and paper guides of my invention.

In a com anion application filed of even late herewit Sr. No. 172,685 I have included the devices of the present construction, since they are more readily applied to the existing machine and are lighter and more compact.
